. Specification of Letters Patent. Patented Jan..1', 1918.

Application filed August 10, 1915. Serial No. 44,811.

13s it known that I, NORMAN W. s'ronnu, a citizen of the United States,and a resident of Pittsburgh, in the count of Allegheny and State ofPennsylvania, ave invented a new and useful Im rovement in Locomotives,of which the ollowing is a specifical;10X1. i 1' My invention relates toelectriclocomotives, and it has special reference to loco: motives thatare provided with so-called quill drives.

One object of my invention is to provide a locomotive of theabove-indicated character which shall be simple, compact and durable inconstruction and shall embody a pair of vide a. single magnetic tures. i

of driving wheels 2i1 twin driving motorsthat are rigidly securedtogether andhave a single magnetic path for their several armatures, allof which are mechemically associated with a single quill which isdisposed in an opening intermediate s'aid motors and is resilientlyassociated with the driving wheels. Another object of my invention is toprovide-a single driving unit which shall comrise a pair of twin motorsdisposed in sidey-side relation and each embodying a pair of armatures,the motors being rigidly bolt- -ed to ther atthe top andhaving aremovable intermediate block of magnetizable ma- *terial between thebottom portions thereof, and field magnet projections associated withthe several armatures and adapted to propath for-said arma- My inventionis best understood by reference to the accompanying drawing, in whichFigure 1 is 'a. view, partially in section and partiallyin endelevation,of a portion. of a ocomotive' constructed in accordance with myinvention; Fig. 2- is a view, partiall in section and partia ly in sideelevation, 0 the structure shown in Fig. 1, and Fig. 3 is a sideelevation of a portion of the driving mechanism shown in-Fi'gs. 1 and 2,

shown comprises .side frames 1, ap urality an axle13, a quill; 4, 59.plurality of" gear w eels 5, flexible driving connectlons 6 between thegear wheels an the adjacent driving wheels and a driving. unit 8comprising a pair of and 10 that are disposed on oppositesides' of theaxle 3 and qu ll t and are respectively provided with .arn gatures and12, snare and 2 5, constituting the lower set.-

. lugs or 'fian plurality of olts. 44 extend for the purpose twin motors9 the dotted line.

and 14 that are connected at both ends to the gears 5 by means ofpinions 16, 17 18 and 19,-respectively. V Q The twin motors 9 and 10 areof similar construction, and, therefore, only one of them willbedescribed in detail. The twin motor 9, for instance, embodies the'twoarmatures 11 and 12 that are disposedverti- -cally,'the one over theother, and are inolosed by'a single magnetizable frame 21 whichcompletely surrounds the armatures and is provided with two sets of mainpolar projections'that respectively comprise projections 22 and-23,constituting the upper set, amsi 24:

aid polar projections 22, 23, 24 and 25 are surrounded andmagntized byfield-magnet windings 26, 27, 28 and 29, respectively. Cooperating withthefend portions30 and 31 of the: twin motor 9 are commutating polarprojections 32' and' 33 thatfare respectively provided with field-magnetwindings 34... .and35.

In so far as already described, the twin motors 9 and'lO are similar tothe structures set forth in my co-pending application, Se rial No. 769,204, filed May 22, 1913. The distifitive features of these particulartwin moto (structures, however, will now be more fully set forth. p

The twin motors 9 and 10 are provided with integrally projectingportions 40 and 41 which are located upon the inner adjacent sidesthereof and are positioned substantially in the plane of the upper setsof main polar projections 22 and 23. The frames 21 are also providedwithlupwardly rejecting 42- and 43 throng which a of rigidlysecuring-together the upper portions of the twin motors 9 and .10; 'Insubstantially the plane of the lower sets of main rojections 24 and 25,is located a "re- {polar e block -46 of magnetizablematerial movab whichis rigidly securedin place by means of 100 bolts 47 that project throughlugs or flanges 48 and 49 having anintegral association with therespective twinmotor structures 9' and 10.

The peculiar 'arran ment and location of 1 06 parts set forth rovi e asinglemain magnetic circuit-whichthreads allof the armatures 11, 12, 1ssnarl and is .indicated by By reason, thereof a" particularlycompact,1ight"and relativel supported upon suitable cross-ties 50 v bymeansof integral projections 51 between the respective side frames 1which may be of any suitable construction.

The axle -3 and quill 4 are concentrically related, and suflicient spaceis provided be tween them' to permit of slight relative movement, suchas is caused by the irreg larities and unevenness of the track or rails.The uill 4 is rotatably mounted in a plurality'o end bearings 52 and 53,and the respective endsvthereof-are provided with the gear wheels 5,with which the several armature 'inions 16, 17, 18 and 19 mesh, wherebythe riving efiort of all of the armatures 1s transmitted through thegear wheels 5.

Each of the gear wheels 5 is provided with laterally projecting arms 54that extend out- .ing driving wheel 2. 1 Between the spo and the gearwheel arms 54 are position from thescope and spirit o my invent-ion.v

wardly between spokes 55 of the corresgongi;

driving-springs 56 for thepurpose of p viding a resilient or yieldingdriving connection between the gear wheels 5 and therespective drivingwheels 2, as has been accomplished in the prior art,

O viously, my. invention isjnot restricted to the specificalstructuraldetails and 'arrangement and location of parts shown anddescribed, as the benefits thereof may be $6- cured by means ofstructures differing materially therefrom, but makin no'departure Idesire,-thei-efore, that onl such limitations supporting frame, and aplurality of twin wheels,
